I worked as a swimming instructor for many years and I would add: when your children are old enough, teach them how to be rescued (don�?t panic, float on back, learn how to be pulled in to safety) and teach them to rescue someone without getting wet (eg lie down on the side of the pool and use a broomstick or similar to pull the person to safety at the side of the pool and talk to them the whole time). When adults drown, quite often it is because they jump in before assessing the dangers to themselves. Self preservation with rescues can be taught young. Also, watch out for buckets of water – it is enough to drown a small child if the overbalance.
